| @inzwetrust: spread is not a formation, it's more of a philosophy. There are a bunch of formations that might be used in a spread system. Triple option is not a formation, it is a type of play that can be run out of multiple formations. Wishbone is a formation, but by no means is it common anymore. It was in the 1970s and 1980s, but now it is outdated and rarely used. The pistol is becoming common in college, but not in the NFL, so that will depend on the author's definition. And the a-11 is not common at all, it is in fact illegal in college and the NFL and will soon be illegal in California, the state where it was being used in high school. |
